DESCRIPTION:Traditionally\, embedded systems were simple enough that an ini
 tramfs was not needed at all.\nThis has changed in the last recent years w
 ith new requirements\, often related to verified boot.\nThat means that ad
 ditional steps are now needed before the rootfs can be mounted.\n\nExistin
 g solutions\, such as the Yocto initramfs-framework have significant drawb
 acks. The resulting initramfs is quite big (multiple megabytes) which has 
 a noticeable impact on the boot time. And while the shell scripts make it 
 easy to customize\, robust error handling is difficult.\n\nIn this talk\, 
 Michael will introduce [rsinit](https://github.com/pengutronix/rsinit)\, a
  single-binary-initramfs for embedded systems\, written entirely in Rust.\
 nIt is tiny (less than 200 KiB)\, very fast and "just works" for simple us
 e-cases. Alternatively\, it can be uses as a library to build a fully cust
 om binary.\n\nBeyond being small\, it brings the full power of Rust to the
  initramfs\, which allows building additional features (such as splash scr
 eens or read-ahead) without pulling in further dependencies.\n\nMichael wi
 ll present the existing features\, explain the design choices and give an 
 overview of what is planed for the future.
